  • Patent number: 8605334
    Abstract: A physical layer which depends on hardware of a general-purpose interface determines whether an image supply device supports a predetermined communication protocol. A transport layer which controls communication as an upper layer of the physical layer determines whether the image supply device supports the predetermined communication protocol. When either of the physical and transport layers determines that the image supply device supports the predetermined communication protocol, the image supply device is decided to support the predetermined communication protocol. When both of the physical and transport layers do not determine that the image supply device supports the predetermined communication protocol, an application layer serving as an upper layer of the transport layer determines whether the image supply device supports the predetermined communication protocol.
